Assessing complicated power quality issues off-line with IEC 61000–4–30 compliant toolbox

The first edition of the international standard IEC 61000–4–30 has been published in February 2003. It describes power quality measurement methods. To find fully compliant equipment to this new standard was not a sinecure. The experts from Laborelec (The Belgian competence centre in energy processes and energy use) with the support of Elia (Belgian Transmission System Operator) have decided to benefit from their knowledge in power quality, data acquisition and data processing to develop a compliant toolbox able to assess complicated power quality issues (for a 50 Hz net): the Digital Wave Recorder (DWR).
